ios - 在运行时获取配置文件的到期日期？

Question

我有一个应用程序，我经常通过临时分发方法将其分发给测试人员。这些测试人员中的一些人“随时待命”并且对配置文件和季度到期有足够的了解，并且可以(如果我忘记了)插入我重建一个新版本供他们测试。

然而，一些用户似乎总是到了它停止运行的地步，然后提示和提示它——尽管他们可能不理会 iOS 级别的提醒。

我的问题是，我能否以编程方式在运行时获取到期日期并执行我自己的“应用内”警报或系统通知以提醒他们下载更新版本？

你正在寻找类似的东西

"<key>ExpirationDate</key><date>2014-12-06T00:26:10Z</date>" in [[NSBundle mainBundle] pathForResource:@"embedded" ofType:@"mobileprovision"]

但要做到这一点并不容易!此代码可以改进，部分代码基于其他 stackoverflow 帖子。注意:另一种选择是加载项目 plist 之间的所有内容和/plist 到...一个 plist(字典)。但是因为我们已经在那里了，所以我们只是手动找到 sibling 。

- (NSString*) getExpiry{

    NSString *profilePath = [[NSBundle mainBundle] pathForResource:@"embedded" ofType:@"mobileprovision"];
    // Check provisioning profile existence
    if (profilePath)
    {
        // Get hex representation
        NSData *profileData = [NSData dataWithContentsOfFile:profilePath];
        NSString *profileString = [NSString stringWithFormat:@"%@", profileData];

        // Remove brackets at beginning and end
        profileString = [profileString stringByReplacingCharactersInRange:NSMakeRange(0, 1) withString:@""];
        profileString = [profileString stringByReplacingCharactersInRange:NSMakeRange(profileString.length - 1, 1) withString:@""];

        // Remove spaces
        profileString = [profileString stringByReplacingOccurrencesOfString:@" " withString:@""];


        // Convert hex values to readable characters
        NSMutableString *profileText = [NSMutableString new];
        for (int i = 0; i < profileString.length; i += 2)
        {
            NSString *hexChar = [profileString substringWithRange:NSMakeRange(i, 2)];
            int value = 0;
            sscanf([hexChar cStringUsingEncoding:NSASCIIStringEncoding], "%x", &value);
            [profileText appendFormat:@"%c", (char)value];
        }

        // Remove whitespaces and new lines characters
        NSArray *profileWords = [profileText componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];

        //There must be a better word to search through this as a structure! Need 'date' sibling to <key>ExpirationDate</key>, or use regex
        BOOL sibling = false;
        for (NSString* word in profileWords){
            if ([word isEqualToString:@"<key>ExpirationDate</key>"]){
                NSLog(@"Got to the key, now need the date!");
                sibling = true;
            }
            if (sibling && ([word rangeOfString:@"<date>"].location != NSNotFound)) {
                NSLog(@"Found it, you win!");
                NSLog(@"Expires: %@",word);
                return word;
            }
        }

    }

    return @"";
}
